European Avalanche Danger Scale

The Bulgarian Avalanche Association uses the European Avalanche Danger Scale, the common scale of all avalanche warning services in Europe (EAWS). The danger level in the bulletin describes how stable the snowpack is and how easily an avalanche can be triggered.

Level		Snowpack stability	Likelihood of triggering
5 Very high		The snowpack is poorly bonded and largely unstable in general.	Numerous very large and often extremely large natural avalanches can be expected, even in moderately steep terrain.
4 High		The snowpack is poorly bonded on most steep slopes.	Triggering is likely, even from low additional loads, on many steep slopes. In some cases, numerous large and often very large natural avalanches can be expected.
3 Considerable		The snowpack is moderately to poorly bonded on many steep slopes.	Triggering is possible, even from low additional loads, particularly on the indicated steep slopes. In certain situations some large, and in isolated cases very large natural avalanches are possible.
2 Moderate		The snowpack is only moderately well bonded on some steep slopes; otherwise well bonded in general.	Triggering is possible, primarily from high additional loads, particularly on the indicated steep slopes. Very large natural avalanches are unlikely.
1 Low		The snowpack is well bonded and stable in general.	Triggering is generally possible only from high additional loads in isolated areas of very steep, extreme terrain. Only small and medium natural avalanches are possible.
